FUELING BARGE.

To all w 710m t may concern Be it known that l, ARTHUR F. CASE, a. citizen of the United States, residing` at Cleveland, in the countyof Cuyahoga and State of Chio, have invented a certain new and useful Improvement in a Fueling Barge, of which the following` is a full,'clea,r, and exact description.

rihe present invention relates to a fueling barge for fueling` steamships. The principal object of the inventionis to provide an ellicient boat fueling machine or apparatus which has the advantage of considerable storage capacity, which is adaptable for feeding fuel into hatches which are on the top of the boat7 or for side hatch fueling7 and which raises the coal or fuel only to a height necessary to feed into theproper hatch without requiring that it be elevated to a considerable height above the hatch. as is necessary with the so-called gravity systems.

Further the invention aims to provide a .fueling barge carrying; means by which the barge itself may be loaded with fuel, L- s by a revolving' derriclr carrying a grab bucket.y and also means by which the fuel is discharged from the vbarge into a steamboat through the medium of a conveyor on a laterally extending boom 'to which coal is delivered, and which is capable of boing moved up and down a tower, and may be tilted about its inner end or swung1 horizontally so that the material may be discharged at just the right height, and at the proper hatch without elevating .the fuel any higher than necessary, the whole being so constructed that though it operates very effectively in fueling` a boat irrespective of the heigrhtof the hatch openings or their distribution along the length of the boat, but never ieless when the barge is being` conveyed. 'from point to point, the movable parts utilized in loading` and unloading the barge can be lowered so as to avoid excess of superstructure which might produce instability.

The above and other objects are attained by my invention which may be here briefly summarized as consistingV in certain novel details of construction and combinations and arrangements of parts which will be described in the specification and set forth in the appended claims.

By wayof preliminary explanation it might be mentioned that my improved fueling bai-,efe has a series of storage hoppers preferably arranged in sets or groups to which fuel is adapted to be delivered in fuelin@` the barge by `any suitable conveying mechanism lwhich is preferably supported at one end of thebarge, and in `this case consists of a revolving` derrick carrying ahoisting and conveying; bucket which delivers they fuel into suitable hoppers so arranged that the fuel may be carried from these hoppers to the storage hoppers. For the purpose of filling and also emptying` the storage hoppers, as when a boat is being fueled, a series of conveyors areutilized, each serv- ,ing one set of the storage hoppers, andarranged to travel in a closed circuit overthe storage hoppers in connection with which suitable gates or doors are employed for` the admission of fuel, therein, then downwardly and alongbeneath the storage hoppers which have suitable chutes or delivery orifices arranged so that the fuel mav be discharged from the bottoms of the 'hoppezs 110 irang'ed substantially in the hoppers in each set,

onto the lower traveling flights of these conveyors. The lower sections of these conveyors which receive and deliver the fuel from the bottoms of the storage hoppers9 carry the fuel toward the transverse center line of the barge and discharge the fuel onto transverse conveyors which in turn deliver the fuel to an elevator boot.

From this boot the fuel is conveyedy by the elevator composed of chains and elevating' buckets which travel up the tower positioned or adjacent the center of the barge) this elevator passing' around a tripper and discharging' into a hopper which delivers the fuel onto a conveyor carried by a deliv ery booin which delivers the fuel into the boat hatches, this tripper and the boom as well as other parts associated therewith forming' a unit which can be raised and lowered along' the tower in accordance with the required delivery height of the fuel. ridditionally the unit has provision for turning the boom antL for swinging' it about transverse axis near its inner end, so that its delivery end may be raised and lowered kwithout elevating' or lowering the unit as a whole.

The above general or preliminary explanation will make clear the following detailedexplanation of the construction ant operation.

The barge 10 in this instance contains four sets or groups of storage hoppers ar- "our quarters of the boatand designated res c r,tively ll. llh 1l and 11d? there being' in this case four The two pji'oups ll and 11d Yand the two groups llh and llc are respectively arranged on opposite sides of the longitudinal center line of the barge. and the two groups lla and l'lb are arranged on one side of a transverse plane through the barge near the center7 and the two groups ll and 11d are on the opposite side of the same.

To charge or fill these hoppers the bara-e is provided at one end with a revolving; derrick 12v, of customary desigrm construction and operation. mounted so that it may be swung' laterally`r and raised and lowered about its inner or lower endl The derrick carries a hoisting and conveying` bucket- 13. which may be of the clam-shell type` and which will have such capacity that a fairly large quantity of fuel can be delivered to the barge at one trip of the bucket. 1t will be understood that with this hoisting' and conveying' apparatus including the derriclt and bucket, fuel may be loaded onto the barge from any suitable source of supply whichniay be on a pier alongside of which the barge may be tied or anchored, or which may be on another barge alongside the fueling barge. As a matter of fact, fuel may be loaded into the fueling` barge at the saine ,center line of the barge.

time that it is being delivered therefrom to fuel a boa-t, or it may be delivered into the barge while the fueling' apparatus is idle.

rllhe bucket 1B delivers the fuel into two hoppers lll, le, located near the center of the barge on opposite sides of the longitudinal From these hoppers 14, la, the fuel is delivered by delivery spouts l5a to four conveyors 16, two extend ingv forwardly in parallel lines or planes, and delivering' fuel to two sets of storage hoppers lla and 11", and two extending' rearwardly in parallel lines or planes and delivering fuel to the sets of storage hoppers 11c and lla. Each of these conveyors includes two endless chains connected together with scraper plates or blades 16a (sce Figi'. 5) and extending` horizontally over one set of hoppers this section of the conveyor' traveling' from the center toward the end of the barge. Then the conveyor travels vertically downward to nearly the bottom of the barge. then horizontally inward toward the center. and up to the upper level. These conveyors each pass about suitably positioned pairs of sprockets 16h, and they are preferably driven by four separate motors 16 located adjacent the outer ends of the conveyors and each suitably geared to one pair of sprockets.

The upper sections of the conveyors scrape the fuel along horizontal troughs 17, see particularly Fig'. 57 which are on top of the storage hoppersv and the fuel may pass from these troughs as it is moved along the same throue'h doors or `gates 18 which are g'aoviiled in the bottom of each trough, one over each hopper. These 2gates or doors may be of any suitable form.y and operated in any desired manner. but in this instance they are of the sliding' type.. being' adapted to be moved in and out by horizontal lateral arms 1Q having' racks. each engaged by a pinion 2O on the lower end of a vertical shaft 521 on top of which is a hand-wheel 22. These hand-wheels are on opposite sides of walks Q3. which extend forwardly and rearwardly lengthwise of the boat, one between the hoppers 11a and 1l, and the other between the `hoppers llC and 11d. This is clearly indicated in Fig. 5. llVith this con struction.,y any of the hoppers can be filled by opening' the gates and the supply of fuel thereto may be terminated by closing the `gates.

These same conveyors are employed in removing the fuel from the storage heppers when it is desired to fuel a boat. and to that end the lower horizontal traveling' sections of the conveyors travel along?l lower troughs 24, which are beneath the delivery chutes 25 at the lower ends of the hoppers. The plates or blades 16a of the conveyors 16 scrape the fuel along these troughs inwardly toward the center of the baro'e where the troughs extend upwardly as shown at 2in in Fig. 6, and at their inner ends these troughs have delivery pans or aprons 25, (see Figs. 5 and 6) which deliver the fuel onto two inclined cross conveyors 2G shown in F ig. 5, which may be motor driven through gearing indicated at 26, cach conveyor 2GA comprising` chains with scraper blades 26il (see F igs. 5 and 6), and operating in inclined troughs 27 the chains passing` about sprockets 26b shown in Figs. 5 and 6, That is to say, the fuel is delivered from the sets of storage hoppers l1EL and 11d into the trough of one cross-conveyor, and the fuel from the other two sets of storage hoppers 11b and llc is delivered into the trough of the other cross-conveyor.

The inner ends of these conveyor troughs discharge the fuel near the Center of the barge into an elevator boot 2S (Figs, l, 5, and 6), and from this boot the fuel is carried upwardly by an elevator composed of chains 29 having a series of elevatingbuckets 30, the fuel being elevated in a vertical tower 3l which stands up from near the center of the barge. This tower is shown only conventionally inasmuch as it may be formed of structural material in any suitable manner, it being important only that it effectively support the delivery apparatus which is' movable up and down the tower and which delivers the fuel into the hatches.

The chains 29 of the elevator pass around lower sprockets 32T suitably mounted in the boot 28, and around similar sprockets mounted at the top of the tower.

Between the upper and lower sprockets the elevator chains pass around a tripper which causes the material to be dische red from the buckets7 this tripper forinn part of the apparatus includingthe delivery boom and constituting the unit movable up and down the tower, it being;` understood that 'the height to which the fuel is elevated by this elevator may be varied by raisins` and lowering` the vertically movable unit. The tripper includes sprockets 34 and 35., over which tho elevator chains carrying the loaded buckets travel. (see Fin: 6), the chains making a loop around the sprockets 34 and 35 so as to tip the buckets and cause the fuel to be discharged therefrom in a well known inan- From the sprockets 35' the chains of the elevator pass around additional tripper sprockets 3G which are directly above the before mentioned sprockets 3er and from these sprockets the chains pass upwardly 7), supported on a platform 38. ff y minei a part of the unit which moves up and d-'iwn the tower. yThe motor drives the elevator through the medium of a pinion. 39 whichI meshes with a gear 40 on a shaft 11, having a pinion which driv s a gear 43 on a shaft Lillto which the sprockets 35 are ate tached.

The unit which moves up and down the tower is shown separate froni the tower in Fig. G, all the apiaratus shown by full. lines except that at the bottoni of Fig. 67 and which serves to deliver the fuel to the elevator boot, forming); the unit which .moves along the tower.

By reference to Figs. i', S. and 9, it will lie-observed that the unit is provided with suit-ably flanged` wheels l5? which engage vertical grinding and supporting rails /ll secured to opposite sides of vertical channels 47. The unit can be raised and'lowered by a suitable hoistingl and lowering apparatus including' a n'iotor driven drum (not shown) which will be mounted on the barge near the base of the tower.y and which receives a hoisting; and lowering cable which l have indicated at e8 `in Fig. 6. This cable 48 is preferably dead-ended at the top of the tower. as shown L9 in F 6, and then passes downwardly around sheave 50 (Fing. 6) carried by the vertically movable unit, then upwardly around a sheave 5l Fiss. l

`and 6) supported at the top of the tower,

and then down to the hoisting; and lowering` drum. f llllhen the elevator chains and b1, Ikets pass around the tripper the fuel is delivered into a chute52 which extends downwardly be ieath th" pl tforni 3d near the top of the r as before e lained. This chute doe livers the fuel into a hopper 53 mounted 'on end of a delivery booin 54, `which d so that it may be swung' about transverse axis to raise or lower its outer ond. and may be swung' about a vertical axis to deliver the fuel at, any angle within substantially a half circle with reference to the longitudinal axis yof the barge. rlhe hopper 53 discharges the fuel onto a belt conveyor 55., whichv carries the fuel out to the outer end of the booin7 and which travels around main sheaves or drums 56 and 57 at the inner and outer ends of the hoorn7 and aroundother suitable sugplnting` rollers or sheaves 54s, the top les; ory section of the conveyor belt being;- dished.` with its edges The boom is pivotally mounted (by means to be hereinafter described) at the top' of a vertical supporting arm 59. (see Fig. (i) which at its lower end is rotatably supported through the medium of a ball and socket step bearing 60, the socket part of the bean ing being carried by a support 61 at the bottoni of the vertically movable unit. The arm 59 passes through and is adapted to turn with a platform or turntable 62, on the lower side of which are r tably supported a series of guide rollers "3 (see i lgs. 6 and 9), which rollers engage the inner periphery of a circular guide track fel, on the outer periphery of which is a rack segment 65. T his rack segment is engaged by a pinion 66 (see Fig. 6), mounted on a short vertical shaft 67, carried by the platform 62, and provided at its upper end with a bevel gear 68 (see FiV 6 and 9), designed to be rotated by a bevel 69 on the short horizontal shaft 70 having a gear 71 engaged by a pinion 72 on a shaft 73, provided` with a sprocket 7d, these driving gears, shafts and the like being` all carried by the )lat-forni 62, as wil Figs. 6 and 9. 1t will be understood that when the sprocket 74 is turned, the booni 541-, supporting arin 59, and platform 62 will be turned about the axis of the circular trackway 641-. The sprocket 7eY is driven by a chain 100, hereinafter described.

To tilt the booin about its pivotal axis, the following` Inechanisin is shown, particularly in Figs. 6 and 9. The inner end of the boom which projects a short distance rearwardly of the pivotal axis is connected bya pair of straps 75 to a nut 76 adapted to travel up and down athreaded vertical shaft 77. To turn this shaft iu either direction there is provided or the lov, er part of the shaft a bevel gear .38 which gaged by a bevel gear 79 live'. cured to a short horizontal shi vided with a gear .81 which drive pinion 82 on a horizontal shaft 8S, p with a sprocket y84. 1t will be seen that when the sprocket 8l is turned in one direction, the nut 76 will be moved either up or down the threaded shaft 77 so as to raise or lower the outer end of the boom` as the case may be, and when the sprocket 84 is rotated in the opposite direction. the outer end of the booin will be moved in the opposite direction to that in which it was inoved when the sprocket was rotated in the direction first referred to. The parts designated by the reference characters 77 to 8st inclusive, are mounted directly or indirectly on the rotary platform 62. i is will be explained subsequently, the sprocket 8e is rotated by the chain 101.

F or the purpose of driving the delivery belt 55 extending along the hoorn, and for rotating the sprockets 4 and 81twhirh respectively turn and tilt the boom, l mount on a platform 85, (see Fig. 8) carried by one side of the boom supporting arni 59, a motor 86, which through reduction gears, one of which is shown at 87 in Fig. 8, drives a horizontal shaft 88 which extends through piemel OO UO.

.j l n through a chain, indicated at91 in Fig. 8, rotates a sprocket 92 on a shaft 93, which ex- J.

ends through the boom, and on its end opposite to that having the sprocket,` is a pinion 911 which drives a gear 95 fixed to the shaft 96 to which is secured the rear di in 56 about which the delivery belt 55 of the boom passes. 1t will be seen that when the clutch member 89 is shifted so as to clutch the sprocket 90 to the shaft 88, the shaft 96 and dru1n56 are rotated, and this in turn drives the delivery belt 55.

through this saine shaft 88 which drives the delivery belt 55, that the two sprockets 741 and` 8e already referred to, are rotated to swing the boom and to tilt it. For that purpose. the end of the shaft 88 which vprojects through and beyond the boom is provided with a pair of sprockets 97 and 98 (see Fig. 8) either of which is adapted to vbe clutchedV to the shaft 88 by a clutch member 99. Then the sprocket 97 is clutched to the shaft it drives the hoorn rotating sprocket 711 through the niedium of a chain 100, shown in Fig. 6.

lt is TWhen the sprocket 98 is clutched to the shaftI paf ered in connection with the drawings, and by way of recapitulation it might be stated that the storage hoppers are loaded through the f-:winging dcrrick and bucket which deliver the fuel into the hoppers 141- froin which the fuel is taken by the four conveyors 16 and moved along the troughs 17 and delivered into the tops of the storage hoppers when the gates 18 are open. By selectively opening` and closing these gates it is apparent that the hoppers can be filled as desired. 1t was already stated that the filling of the hoppers can take place while the delivery apparatus is idle, or at the sanie tirne that the boat is being fueled. 1n any event, the

sarne conveyors 16 which deliver' the fuel to A the storage hoppers convey the fuel from the lower ends or bottoms of the hoppers to the cross conveyors 26 which discharge the fuel into the elevator boot 28. From this the,

The center of this shaft conentA from the above description consid.

55 ot the boom, and by the latter is carried to and delivered into the boatha-tches.

The boom n.uibel raised and lowered to deliver the ituel at the right height by raising or lowering by means oit the rope yor cable 48 the unit which moves up and dovvn the tower, or it desired, or `4found, `feasible, the height. oit delivery i be variedby simply tilting thc boom. i any rate, with the mechanism Which l have provided,l itisnot necessary to el vat, the Vfuel much it any higher than the hatch openings ot the boat being tueled. This isa. bi advantage over so-called gravity systen'isvrhich require that the :tucl pass by gravity trom some elevated point into the boat li atrhcs. Obviously With my Y.reling apparatus, power is saved by deliveriirl the fuel no higher tl an necessary, and there is a minimum ot lnfealrage.

The boom can be raised and lowered readily, and it can be easily tilted or swung horizontally by the mechanism which l have provided it being understood that the boom is tilted by operating the sprocket chain lOl.l anc is swung laterally by operating the sprocket cha in lOO.

The barge can. be conveyed 'from ypoint to point either by means oit a tua, or it desired, propelling` mlalianism infiv be installed directly von the barge. lllhenthe bar.. isbcing conveyed or propelled troni onebpoint tothe other, the derricl; et the hopper loading apparatus and the unit which moves up and doivn the tower, in.- cluding the boom vill befloivered as close as possible 'to the top or" the storage hoppers so that the center ot gravity will. not be high which makes tor-stabilitv in transit.

To furnish current to energize the several driving motors which operate the different conveyors, which raise and loiver the vertically movable unit along 'theftorveig and y which turn and tilt the boom, an engine generator set is preferably provided on thel barge. f n
